jasoncarreira identity-lookup
Look up who an alias belongs to (people) or what a channel id is (channels) using state/identities.yaml. Use when the operator or a turn-context refers to a platform-prefixed id ("who is discord-100000000000000001?", "what channel is slack-C100?") or you need to resolve aliases the other direction (canonical → display name + aliases). Read-side only — the populator (mimir.identities_populator) maintains the registry.
